To cut a long story short, after leading a revolt against nutrients and the toxicity thereof I have to concluded that as far as plant go and fauna to a certain extent it is been difficult to prove. Instead, deficiencies are much more likely.
There are people still testing and some plants are definitely more finicky than others but these are more ‘specialist plants’, variations on a theme if you like.
There are people working on nutrient ratios too but their work now remains private even to others in the science group. I’m back on EI [emoji5] but only time will tell if Rotalas respond positively. Focus has been placed in co2 and flow as usual and I’m now using liquid carbon daily.
So far so good.
There is a suggestion at the moment that Rotala’s are responding positively to different forms of N. I’m going to try some ammonium hydroxide tonight 0.25ppm......scary [emoji316]
